Colon cancer patients, after surgery, should stay away from greasy foods, especially dinner should not be too full, and eat less meat foods, because these foods can easily stimulate the occurrence of colon polyps. The diet should be based on light and easy-to-digest foods, and more coarse fiber foods, including celery, spinach, cabbage, etc. In addition, vitamin-rich fruits, like oranges, pineapples, oranges and so on, should be increased, and physical function exercises should be performed in moderation. As colon malignancy mainly affects middle-aged and elderly people, they should develop the habit of eating less and more meals, and they should do appropriate activities after eating in order to promote intestinal peristalsis. In addition, we should not work hard and stay up late, and we should have regular colonoscopy, and if colon polyps are found, they should be removed early.
